According to the Sustainable Development Scenario, the power generated by concentrating solar systems will be multiplied by 12 times by 2030 and will achieve nearly 184 TWh. To make it possible it is necessary to combine the concentrating solar systems with other technologies such as photovoltaics, sorption chillers, Stirling engines, etc. The total efficiency of hybrid systems is significantly higher than standalone ones. This paper analyzes​ the possibility of upgrading the existing concentrating solar thermal system with two-focal points located in Cracow, Poland. So far, this installation was used only for water heating applications. To estimate the possibilities of upgrading this system, numerical simulations with the use of Ray Tracing methods and Computational Fluid Dynamics were provided. Data obtained from the ray-tracing analysis allowed to determine the distribution of irradiance for various locations of the receiver. The CFD methods enabled to find the dependencies between the initial parameters of the working fluid, irradiance distribution, and heat transfer efficiency. Obtained results allowed to conclude that it is possible to use generated heat (354 K) for absorption chiller purpose. Moreover, this system may be used for simultaneous heat and electricity production, but firstly some changes in receiver geometry should be introduced.

根据可持续发展情景，到 2030 年，聚光太阳能系统产生的电力将增加 12 倍，将达到近 184 TWh。为了使其成为可能，有必要将聚光太阳能系统与光伏、吸附式冷却器、斯特林发动机等其他技术相结合。混合系统的总效率明显高于独立系统。本文分析了升级位于波兰克拉科夫的两个焦点的现有聚光太阳能热系统的可能性。到目前为止，该装置仅用于水加热应用。为了估计升级该系统的可能性，提供了使用光线追踪方法和计算流体动力学的数值模拟。从光线追踪分析中获得的数据可以确定接收器不同位置的辐照度分布。CFD 方法能够找到工作流体的初始参数、辐照度分布和传热效率之间的相关性。获得的结果可以得出结论，可以将产生的热量 (354 K) 用于吸收式制冷机。此外，该系统可用于同时产生热量和电力，但首先应引入接收器几何形状的一些变化。获得的结果可以得出结论，可以将产生的热量 (354 K) 用于吸收式制冷机。此外，该系统可用于同时产生热量和电力，但首先应引入接收器几何形状的一些变化。获得的结果可以得出结论，可以将产生的热量 (354 K) 用于吸收式制冷机。此外，该系统可用于同时产生热量和电力，但首先应引入接收器几何形状的一些变化。
